Walt I am open to this question, but it did not seem like you answered this
Then where did the witnesses get the "7.65" part if they didn't read it off the rifle?
The Argentine mauser resembles a model 91/38 carcano... At first glance it's easy to mistake the Argentine mauser ( also known as a 7.65 mauser)...because the carcano and the 7.65 ( Argentine) mauser do look similar. Just as a deer hunting rifle is often called a "high powered rifle".... the Argentine is often called a 7.65 mauser.....
Nobody read 7.65 stamped on the Carcano....Weitzman simply referred to the rifle that he could only see a mall portion of as a 7.65 mauser ( meaning an Argentine mauser ...same thing just different way to identify the gun)
Later Weitzman recognized that he was in error and admitted it.....But Roger Craig wouldn't back off....Craig didn't know the 7.65 ( Argentine) mauser from a 03 Springfield ....but he respected Weitzman's first erroneous identification and believed that was what they had found... Craig was wrong....and a pathetic mental case.
